An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
These detentions come after an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt in the event. A total of five individuals went to hospital for treatment and have since been released.
Officers arrested a 31-year-old man for suspected robbery and assault close to the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
